The stave, also called the staff, is a set of five horizontal lines and
four spaces that each represent a different note or musical pitch (Figure 1). The name of the note is
determined by the type of clef that appears
at the beginning of the stave.

In the case of the commonly-used treble clef, and the treble stave that it signifies, the pitches are assigned as in Figure 2.

On the bass stave, indicated by the bass clef, the notes
are arranged as in Figure 3.

The grand stave is the combination of the treble and bass
staves (Figure 4).
